Subject: [for-linus][PATCH 03/17] tracing/hwlat: Drop the duplicate assignment in start_kthread()
Date: Tue, 04 Aug 2020 16:57:46 -0400	[thread overview]
Message-ID: <20200804205812.352602030@goodmis.org> (raw)
In-Reply-To: 20200804205743.419135730@goodmis.org

From: Kevin Hao <haokexin@gmail.com>

We have set 'current_mask' to '&save_cpumask' in its declaration,
so there is no need to assign again.
